Metadata is “data [information] that provides information about other data”.
   
Wikipedia: Search engine optimization
Search engine optimization (SEO) is the process of affecting the online visibility of a website or a web page in a web search engine’s unpaid results—often referred to as “natural”, “organic”, or “earned” results. In general, the earlier (or higher ranked on the search results page), and more frequently a website appears in the search results list, the more visitors it will receive from the search engine’s users; these visitors can then be converted into customers.
